PhoneInfoga
Information gathering framework for phone numbers
PhoneInfoga is an open-source intelligence framework focused on gathering and analyzing information related to international phone numbers. The tool aggregates data from multiple scanners and external services to provide contextual intelligence such as country, carrier, line type, and potential VoIP provider details. It is designed primarily for investigators, analysts, and security researchers who need structured phone-number reconnaissance rather than real-time tracking. PhoneInfoga intentionally avoids automation of invasive actions and instead assists manual investigations by correlating publicly available data. The platform includes both a command-line interface and a web client backed by a REST API, making it suitable for integration into larger investigative workflows. Because it relies heavily on external data sources, its effectiveness depends on proper configuration of scanners and APIs. -
